Storage Spaces Not Writing Data Equally


It's -much- more forward thinking! And what you say about restriping in the background just isn't true. Will Storage Spaces rebalance data and cache, or will the new disk end up unprotected?What are the limits (upper and lower) on column counts for mirror, triple mirror, dual parity? You do it. have a peek here

Only 4-6 hours lost. the cows are here to take me home now... Similarly, you will no longer be contrained by having to add multiple disks (matching the original pool count) in the future - you can add a single disk at a time. I'm evaluating Storage Spaces myself.

I'm really pressed for time since I have to get the shelf redundacy working by tomorrow. yet, of course. In some ways having dual boot is complementary like that. 0 2 months ago Reply Mark Robson3   Zach Congrats on this. It just worked.

  • Long file names and large volume sizes.
  • For your second questions, I am afraid to say that the storage space has no such mechanism to rebalance the usage of each physical drive like RAID.
  • My system is like the polar opposite of yours.
  • If 20 megs changes in one area of a 20 gig virtual machine, your would move 20 gigs with file-level and a max of 256 megs with Storage Spaces.
  • I wanted to ensure that this feature could deliver on the results that Microsoft boasts about.
  • Once you add in 4 physical disks, you can extend the virtual disk.
  • It sounds great and it probably is (I am reserving judgement to some extent depending on long-term reports from the field) but it can be confusing, especially if you use Parity
  • Can you comment on it's ability to use all space on dissimilar size disks, the performance, the expandability with new drives added?

I'm looking at putting together a bunch of JBODs with cheap 4TB NL-SAS drives, and hooking them up to a Windows Server 2012 R2 box or two. My first parity SS setup was terribly slow. Technically, you don't even have to reboot if your motherboard has hot-pluggable SATA ports, or your Storage Space is on USB. 0 1 year ago Reply Mark Robson3 Thanks 0 1 Optimize Storagepool Parity Paid options start at $69 and get you 5 data drive capability, and there is a $120 edition that gets you support for 23 data drives.

Actually no flaw in my system, just didn't disclose my full configuration, because the rest of my system is not broadly applicable. Even with bid pricing, I doubt that will go down to the $22-25k range where it needs to be to fit an R720 head unit and stay within $30k total.Also, Chenbro But the aspects I care about -- self healing, disk scalability, the death of CHKDSK -- are extremely appealing. click site Reply Cary March 29, 2012 at 13:33 # Helge: It is a bug.

But the above confirmation of data resiliency in the face of failure was not good enough for me.

Expandability is another black eye for hardware RAID.

Storage Spaces Rebalance Parity

The drive has to be around 5GB of size to be available in Storage Spaces. http://windowsitpro.com/windows-server-2012-r2/rebalance-data-over-storage-pools Thanks for helping make community forums a great place.

It is better either to have four or more drives, or else drives of equal size. Thursday, December 27, 2012 12:19 AM Reply | Quote 0 Sign in to vote For a feature spec, just look at Drive Bender. If my internal company primetime test of Storage Spaces falters, I definitely won't be ditching my tried and true RAID-1 approach for clients anytime soon. Check This Out One: I want to be able to add drives and actually use the space- would be solved by rebalancing.

No-downtime-required data repair. In the event that ReFS needs to perform deeper repairs on data, there is no need to bring a volume out of availability to perform the recovery. Optimize-volume Again, we need that number of disks to be able to put an additional physical disk at the bottom of each column. I need to expand my data pool with more drive so i am doing some research on how to do it.

I ended up keeping the computer I had storage spaces set up on, and just moving it to my main TV to make it the HTPC in the house. The Testbed: An Old Server and Some SATA Drives My testbed system is an old but still working Dell PowerEdge 840 server. This is discussed here and the following screenshot from my own system clearly shows the unequal utilization of the disks: When adding a new drive to a pool, existing data is Storage Spaces Powershell How good/bad is dual parity performance with largely sequential access pattern and a large WBC?

Enter Drobo. For example, if you have three drives of 100GB each, you could only use two to create a "storage pool". With, say, 4xMD1200, what would be the most efficient way of filling them? http://megathud.com/storage-spaces/storage-spaces-not-in-explorer.html Getting started with the feature only requires one or more drives, in addition to the drive where you have Windows installed.

Thanks.Please remember to click “Mark as Answer” on the post that helps you, and to click “Unmark as Answer” if a marked post does not actually answer your question. I am hoping that day will come, but for now, it's a mechanism for data storage sets only. Drives that have been removed from the pool can be used on any Windows machine without losing data. For starters, the official FreeNAS site recommends at least 8GB on a system running FreeNAS with ZFS -- and they explicitly say that 16GB is the publicly acknowledged sweet spot.

Edit: never mind, found the answer - WBC for a mirrored or parity space will be mirrored, WBC for triple mirror or dual parity space will use triple mirror.What about tiering? All those fancy benefits from ZFS go out the window. I also really have only dabbled in the cloud, so this setup would solve both, plus give me better access to data on my home devices than relying on cloud, constantly Reads on the other hand are just fine at 900mb/s from same.

The next big performance gain will come from switching from SATA drives to M2 drives. If I have to do that, I'll stick with the familiar NTFS, thank you. Even GNU/Linux garbage has ZFS support via the venerable "ZFS on Linux" project. It works best with Server 2k12, but on a stand alone workstation, you run into problems.

While you can easily add new vdevs, the already existing data on the old disks remains there and is never rebalanced onto the new disks.
